Extremely fast IP used to delineate buried landfills

Determining the location of old, poorly documented buried landfills has become a significant concern in many places where development is hindered. Today new methodology provides a means for the efficient acquisition of induced polarization and resistivity data. Case studies of six landfills verified the accuracy of the technique and the acquisition speed of the system. At all sites, IP anomalies (>3 milliseconds) correspond to solid waste verified by drilling and trenching.
